Title: Control method for gas combustion
Inventor: IWAKI MASAHIRO
IPC: F23N1/08
Filed: 1981-08-19
Abstract: PURPOSE:To obtain control characteristics having a little overshooting, by making a gas flow maximum after ignition to a burner. CONSTITUTION:A gas combustor is constituted with a gas burner 1, a gas proportional valve 2 which controls gas quantity to the gas burner 1 continuously, a temperature sensing element 3 which detects a load temperature and a control circuit 4 which increases or decreases a proportional valve current according to a difference between a set temperature and the load temperature. In this device, a gas flow is kept maximum until a temperature difference between the set temperature and the load temperature becomes less than a fixed value, and then the current of the proportional valve 2 is made to vary according to a period required until the temperature difference becomes less than the fixed value. With this, a temperature approaches to the set temperature in a short period and control characteristics having a little overshooting can be obtained, as this device is started at the maximum combustion quantity.

IPC: B29C48/08
Filed: 1987-05-26
Abstract: PURPOSE:To keep the ubiquitous deposition of metals partly on a nozzle as small as possible and to improve corrosion resistance, pinhole resistance, abrasion resistance releasability of the nozzle, by forming the surface of a material comprising iron as a main component whose ratio of rust prevention is at a specified value or less in the case when it is immersed in an antimony compound solution of ethylene glycol. CONSTITUTION:A nozzle for molding is composed of a material at least in its surface whose main component is iron and whose ratio of rust prevention is 20 ppm or less in the case when it is immersed in an antimony compound solution of ethylene glycol. If a raw material whose ratio of rust prevention is higher than 20 ppm, antimony metal formed by reduction of an antimony compound is ubiquitously deposited from the surface of the nozzle for molding on the part where elution easily occurs with the elution of iron ions. As the result, projecting portions are produced on the nozzle surface and they cause the formation of dented stripe-like defects on the extruded polymer film surface. As the raw material whose main component is iron, chromium plating and nickel plating are preferable from the view point of no defect on the surface, abrasion resistance, corrosion resistance, chemical resistance and releasability from polymers.

Title: Device and method for displaying video
Inventor: STEVEN P MACGROW
IPC: G02B27/00
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To obtain a compact and light-weight video display such as virtual reality display glasses by making each adjustment element selectively controllable in two refractive index states, in response to each control signal. SOLUTION: Molecules of a liquid crystal 34 that adjoins an energized strip electrode 52 take one of two different structural arrangements depending the polarity of an electric field. When the molecules take a first arrangement in response to the electric field of a certain polarity, the crystal 34 has a relatively high refractive index with respect to a light in a specific polarized state which proceeds in a fixed direction, and when the molecules take a second arrangement in response to the electric field of a reverse polarity, the crystal 34 has a relatively low refractive index with respect to a light that proceeds in the same and fixed direction.  Here, when the refractive index of the crystal 34 is adequately high, light that travels inside a base plate 12 is no longer reflected by a plate/liquid crystal boundary surface but emerges from the base and enters into the crystal 34 through the electrode 52.

IPC: G06F11/30
Filed: 1993-06-01
Abstract: PURPOSE:To suppress the overhead at the time of execution by letting a random number be the number of history information gathering steps without predicting the number of steps to become an infinite loop. CONSTITUTION:The output of a random number generating mechanism 1 is defined as the history gathering steps. History information that a step right after a loop candidate (2) recorded in a loop storage part 22 indicates is retrieved and compared to delete candidates (2) for the loop which do not match. At this time, history information obtained from a program execution mechanism 3 is prescribed order is retrieved and compared and candidates (2) for the loop which do not match are deleted. When the candidates (2) for the loop are all deleted, reference candidates (R) (3) for a program loop are repeatedly erased.
